Thanks for the comments, Mark and Henry.

I would note, however, that what may start out as a reactive policy can transition into a proactive policy which — in this situation — may buttress existing security to benefit the general public.

The other end of this spectrum entails maintaining the status quo until a potentially much worse incident occurs that prompts an even more reactive policy.

In other words, what may appear to be an isolated incident today may become a disturbing trend tomorrow. Just something to ponder.
